TECHNICAL FIELD

The invention relates generally to employing directional antennas placed on structures, such as poles, or buildings, that provide a wireless network for communicating RF signals between user devices and remotely located resources. Further, in some embodiments, the directional antennas may be coupled to base stations and RF signal repeater devices to manage operation of the wireless network.

BACKGROUND

Mobile devices have become the primary mode of wireless communication for most people throughout the world. In the first few generations of wireless communication networks, mobile devices were generally used for voice communication, text messages, and somewhat limited internet access. Newer generations of wireless communication networks have increased bandwidth and lowered latency enough to provide substantially more services to mobile device users, such as purchasing products, paying invoices, streaming movies, playing video games, online learning, dating, and more. Also, for each new generation of wireless communication network, the frequency and strength of the wireless signals are generally increased to provide even more bandwidth with less latency.

Unfortunately, the higher a frequency of a wireless signal, the greater the attenuation of wireless signals passing through physical barriers and over shorter distances than lower frequency wireless signals. Moreover, since the recent rollout of 5^(th) generation (5G) wireless communication networks that can use wireless signals with millimeter waveforms at gigahertz frequencies, it has become even more difficult to provide access to these 5G wireless networks for mobile devices due to these physical barriers.

The present invention now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific embodiments by which the invention may be practiced. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Among other things, the present invention may be embodied as methods or devices. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense. As used herein, “base station” refers to a type of wireless communication device, or a network computing device, that facilitates wireless communication between a wireless network and a plurality of different types of wireless computing devices employed by users, which can also be referred to as user equipment (UE). A wireless base station uses information provided by a link to remote computing resources to generate an RF signal (downlink) that is communicated to other wireless computing devices. Also, the wireless base station is arranged to receive an RF signal (uplink) that includes information from other wireless devices. The uplink information is extracted from the RF signal and forwarded by another link to remote computing resources. In one or more embodiments, these links may employ optical fiber and/or microwave signals to communicate information between the wireless base station and the remote computing resources, such as a Network Operations Center (NOC).

Additionally, in one or more embodiments, the wireless network can employ any type of wireless communication protocol or wired/wireless technologies. Also, as used herein, gNodeB”, or “gNb” refers to a particular type of base station that facilitates wireless communication between a 5^(th) generation (5G) or higher wireless network that utilizes New Radio (NR) technology and a plurality of different types of wireless computing devices employed by users. A 5G wireless network may be deployed with two frequency ranges for the wireless signals. The first frequency range may be a Sub-6 GigaHertz wave band and the second frequency range may be millimeter wave bands (mmWave), i.e., 24.25 GigaHertz to 52.6 GigaHertz. The mmWave bands can communicate wireless signals at a higher bandwidth but have a short range than wireless signals communicated at the Sub-6 GigaHertz wave band at a lower bandwidth.

As used herein, “Internet of Things”, “IoT” or “IOT” refers to an architecture for one or more types of networked elements, such as components, applications, systems, or devices. In one or more embodiments, IoT elements are networked together to provide wireless and/or wired communication and other services between an element management system (EMS) and a plurality of remotely located RF signal repeater devices arranged as donor unit devices and/or server unit devices in one or more 5^(th) generation (5G) or greater generation wireless networks. Further, the IoT elements may also be employed to monitor, store, collect, pre-process, and analyze various types of data and information from the remotely located RF signal repeater devices. Also, the IoT network enables the EMS to employ a beam management application (BMA) to monitor and control the operation of the plurality of RF signal repeater devices.

As used herein, an element management system (EMS) refers to a platform or application that manages communication provided by one or more types of telecommunication elements in a network. Typically, the EMS manages the functions and capabilities of each element but does not manage the network traffic between different elements in a network. To support management of the network traffic between the EMS and other elements, the EMS communicates upward to a higher-level network management system (NMS). In one or more embodiments, the network for the EMS and the other elements is arranged as an Internet of Things (IoT) network to provide at least a portion of the NMS functionality and interoperability between each element in the IoT network.

The following briefly describes the embodiments of the invention to provide a basic understanding of some aspects of the invention. This brief description is not intended as an extensive overview. It is not intended to identify key or critical elements, or to delineate or otherwise narrow the scope. Its purpose is merely to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

Briefly stated, various embodiments of the invention are directed to a method, apparatus, or system that employs a beam management application (BMA) that performs a plurality of actions, including monitoring, commissioning, upgrading, analyzing, load balancing, remediating, and optimizing the operation, control, and maintenance of a plurality of remotely located RF signal repeater devices. The RF signal repeater devices are arranged to operate as donor unit devices and/or service unit devices that route communication of wireless signals between one or more wireless base stations and one or more other donor unit devices, other service unit devices, customer premises equipment (CPE), and user equipment (UEs) over one or more wireless networks. Further, the BMA enables users, such as administrative users, installation technicians, and other network stakeholders to remotely control and operate a plurality of remotely located RF signal repeater devices that route communication between a wireless base station and a plurality of UEs on one or more wireless networks. Further, the donor unit devices may be arranged to provide wireless communication between a wireless base station and one or more other donor unit devices or service unit devices. Also, the service unit devices may be arranged to provide wireless communication between one or more donor unit devices or wireless base stations and one or more CPEs or UEs.

In one or more embodiments, the RF wireless signals may be represented by millimeter waveforms (mmWave) at gigahertz frequencies via 5^(th) Generation (5G) communication protocols, such as 5g New Radio (5G NR) that are communicated over the wireless network between various nodes, e.g., gNbs, donor unit devices, service unit devices, CPEs, UEs, and other wireless computing devices. In one or more embodiments, the RF wireless signals having millimeter waveforms may be arranged as a beam waveform that is radiated in a direction at an azimuth and elevation of a physical location of a node in the wireless network. Also, in one or more embodiments the RF signal repeater devices communicate the millimeter waveforms of the 5G wireless signals in a selected beam waveform radiated by one or more beam forming antennas that includes a selectable shape, direction, strength, and/or phase for the beam waveform directed towards a determined location of another RF signal repeater device and/or an identified UE during a scheduled time period that may be allocated in a pointing schedule.

Also, in one or more embodiments, one or more portions of the RF wireless signals may be communicated with lesser frequencies non-millimeter waveforms via 4^(th) Generation (4G) communication protocols, such as Long Term Evolution (LTE), and the like. Further, RF wireless signals that provide control for one or more RF repeater devices may be communicated via 4G, or less, communication protocols to reduce attenuation of these control signals passing through physical barriers, lower energy consumption, and/or save costs.

For example, in one or more embodiments, a service unit device may employ a first antenna to communicate RF signals via 5G protocols with one or more donor unit devices or remote base stations. Also, the service unit device may then repeat these RF signals with a second antenna via 5G protocols and/or a third antenna via 4G protocols to various other nodes, e.g., CPEs, UEs or other wireless computing devices.

Additionally, in one or more embodiments, a service unit device may employ a first antenna arranged to communicate RF signals in beam waveforms via 5G or higher generation protocols with one or more donor unit devices or remote wireless base stations. Also, the service unit device may employ a second antenna arranged to repeat these RF signals arranged in non-beam waveforms via 5G, 4G or lesser generation protocols to various other nodes, e.g., CPEs, UEs or other wireless computing devices.

In one or more embodiments, the CPE may be any terminal device and/or associated communication equipment located at a customer's location and/or premises and can provide communication over one or more telecommunication channels provided by a telecommunication carrier. The CPE is typically established at a location in a structure separate from other communication equipment provided by a carrier or some other communication service provider. The CPE may include one or more IP telephones, mobile phones, routers, network switches, residential gateways, set top television boxes, home network adapters, or the like.

Also, in one or more embodiments, the RF signal repeater devices may employ one or more beam forming antennas, which may include one or more holographic metasurface antennas (HMAs), or any other type of holographic beam forming antennas (HBFs). An HMA may use an arrangement of controllable elements to produce an object wave. Also, in one or more embodiments, the controllable elements may employ individual electronic circuits that have two or more different states. In this way, an object wave can be modified by changing the states of the electronic circuits for one or more of the controllable elements. A control function, such as a hologram function, can be employed to define a current state of the individual controllable elements for a particular object wave. In one or more embodiments, the hologram function can be predetermined or dynamically created in real time in response to various inputs and/or conditions. In one or more embodiments, a library of predetermined hologram functions may be provided. In the one or more embodiments, any type of HBF can be used that is arranged to produce the beam waveforms described herein.

In one or more embodiments, an RF signal repeater device may include one or more of an HBF antenna, a parabolic antenna, a spherical antenna, a helical antenna, a yagi antenna, a horn antenna, or a phased array antenna. Also, in one or more embodiments, the frequencies of the uplink and/or downlink wireless signals may vary widely, e.g., as low as 600 Mega Hertz or as high as 72 Giga Hertz.

In one or more embodiments, an RF signal repeater device may identify and decode a protocol for wireless control signals included in monitored wireless signals that are used to separately identify each UE and corresponding location along with an allocation schedule that includes allocated transmit/receive time periods in the allocation schedule for each identified UE to communicate wireless signals between a wireless base station and each identified UE.

In one or more embodiments, one or more networks of Internet of Things (IoT) elements may be employed to provide distributed and scalable communication for the BMA to control and monitor one or more remotely located RF signal repeater devices, such as donor unit devices and/or service unit devices, in one or more 5G or greater generation wireless communication networks. For example, the types of control for the plurality of RF signal repeater devices may include one or more of raster scan, azimuth, elevation, gain, waveform, commission, upgrade, updates, and diagnostics. Also, the types of monitoring may include measurement of load, bandwidth, throughput, latency, jitter, error rate, data rate, energy efficiency, and quality of service.

In one or more embodiments, one or more IoT network may employ one or more protocols to communicate with the RF signal repeater devices, e.g., the Message Queuing Telemetry Transport (MQTT) protocol. Further, in one or more embodiments, a separate Certificate Authority may be provided to validate one or more cryptographic certificates provided by the RF signal repeater devices in a request for registration to the BMA. Once the RF signal repeater device's cryptographic certificate is validated, the BMA registers the RF signal repeater device and begins monitoring and controlling the operation of the registered RF signal repeater device. Also, in one or more embodiments, one or more types of public key cryptographic certificates may be employed to validate and register RF signal repeater devices, such as those that conform to the X.509 standard that are used in one or more of the Transport Layer Security (TLS), Socket Security Layer (SSL), HyperText Transport Protocol Security (HTTPS) protocols, or the like.

In one or more embodiments, a user may login to the BMA with a secure remotely managed user and password schema. Further, each user may be assigned one or more different roles, which may provide access for each role to different scopes of functionality and information. Also, once a user's login is authenticated, Java Script Object Notation (JSON) web tokens (JWT) are assigned. In this way, subsequent API command calls for a period of time, e.g., 24 hours, may be executed on behalf of the user based on validation of the JWT by a remote security authority.

In one or more embodiments, the remotely located RF signal repeater devices may be arranged as elements included in a new, extended, or existing IoT network. Further, the IoT network may employ an IoT gateway and/or hub to employ machine learning to provision a virtualized digital twin element in a remote computing environment for each RF signal repeater device. Also, the digital element twin may be employed to model mirrored characteristics, parameters, firmware versions, and key performance indicator values of the actual RF signal repeater device so that various changes to these characteristics, parameters, firmware versions and the effect of these changes, if any, on key performance indicator (KPI) values may be first simulated by the digital twin element before modifying control or operation of the actual RF signal repeater device. Additionally, one or more updates, such as software, firmware, or the like, may first be provisioned at the digital twin element for modeling, simulation and testing. Once the modeled simulation and test results are approved for the digital twin element, the one or more updates may be provisioned on the actual corresponding RF signal repeater device.

In one or more embodiments, key performance indicators (KPIs) for the wireless network and/or RF signal repeater device are selectable by the user and may include one or more of system up time, RF power level, device temperature, polarization downlink over time, polarization uplink over time, quality of service or the like.

In one or more embodiments, the BMA provides for automation of dynamic and real time remediation and optimization of one or more determined values associated with network traffic communicated over one or more RF wireless communication networks. For example, these one or more values may be associated with bandwidth, throughput, latency, jitter, error rate, data rate, energy efficiency, quality of service, and the like.

In one or more embodiments, the BMA may provide for recommendations and/or automated remediation of one or more of wireless network communication anomalies, out of range network communication threshold values, or network communication outages over one or more portions of the wireless or wired communication networks. For example, the BMA may automatically recommend actions to remediate a network communication outage by pre-determining or determining in real time alternative network traffic routes that are presented to the user. Also, the BMA may be arranged to automatically remediate the outage by rerouting network traffic over one or more of the alternative network traffic routes for at least that portion of a wireless communication network that is experiencing an outage. Further, the recommendations and/or automated remediation may be provided for different types of wireless network topologies employed by the wireless communication networks, including one or more of mesh, star, fully connected, bus, tree, ring, or line.

In one or more embodiments, the BMA provides for employing machine learning to generate one or more models of network traffic on the one or more wireless networks and one or more other models for the operation of at least a portion of the RF signal repeater devices available on the wireless networks. Further, the one or more network traffic models and the one or more RF signal repeater device operation models may be employed to provide predictive and/or real time recommended actions and/or automated remediation actions to KPI anomalies and network outages. Additionally, one or more of the network models or the operation models may be iteratively revised dynamically and/or in real time based on one or more of modifications, maintenance, KPI anomalies, updates, or revisions affecting one or more of the network traffic, RF signal repeater devices, or one or more portions of the wireless networks. Further, in one or more embodiments, anomalies may be associated with one or more of a non-expected change to a configuration and/or a parameter value for a wireless device or a service, an alarm associated with the wireless networks and/or wireless devices, or execution of a remediation action to cure/self-heal one or more detected issues, such as an outage or a non-expected change.

In one or more embodiments, the BMA provides an Application Programming Interface (API), and or a user interface (UI), such as a dashboard for a desktop computing device or a mobile computing device to enable a user to monitor and control the remotely located RF signal repeater devices. The monitoring and control may include one or more of commissioning, upgrading, maintaining, analyzing, registering, and load balancing the one or more RF signal repeater devices on one or more wireless networks.

In one or more embodiments, the BMA employs a separate wireless and/or wired communication channel to monitor and control a plurality of RF signal repeater devices on one or more wireless networks. Further, the separate wireless and/or wired communication channel may employ one or more communication protocols, other than 5G protocols, that are omnidirectional and available to communicate control related commands to for the RF signal repeater devices. These other communication protocols may include one or more of Long Term Evolution (LTE), WiFi, ethernet, or the like. Also, in one or more embodiments, an IoT network may be arranged to provide at least a portion of the separate wireless and/or wired communication channel for the BMA to monitor and control a plurality of remotely located RF signal repeater devices on one or more wireless networks.

In one or more embodiments, one or more alerts and/or alarms may be provided by the BMA in the UI for display to users and/or through API commands for other applications such as an Element Management System (EMS), or the like. The one or more alarms may include selectable display and/or publication of an alert/alarm message for one or more types of alarm/alert conditions requiring immediate or future attention of the user. The alarm/alert conditions may include one or more of: (1) a temperature value for an RF signal repeater device that is outside a threshold or range of operational or ambient temperatures; (2) no response by an RF signal repeater device to a watchdog timer and/or a heartbeat signal provided by an IoT hub; and (3) customer premises equipment (CPE) or UE that is unable to connect to a wireless base station because their connection to the wireless base station through one or more RF signal repeater devices is lost.

In one or more embodiments, the BMA may automatically detect one or more different anomalies in key performance indicators (KPIs). Also, the BMA may also be arranged to automatically apply one or more remediation actions to compensate for the one or more detected anomalies.

In one or more embodiments, the BMA can automatically trigger “heatmap audits” such as raster scan searches for improved wireless communication with one or more wireless base stations or other RF signal repeater devices by at least a portion of the RF signal repeater devices affected by a maintenance procedure either prior to or during maintenance procedures. These automatic raster scan searches are employed to identify one or more available “donor” RF signal repeater devices or wireless base stations in the wireless network that are not subject to the maintenance procedure and have a largest overall capacity and capability to replace each RF signal repeater device that may be subject to the maintenance procedures. Further, the BMA may be arranged to automatically switch over network traffic to the one or more donor RF signal repeater devices during or prior to maintenance procedures.

In one or more embodiments, the BMA may employ one or more RF signal repeater devices to “sniff” out and decode protocols for the network traffic associated with one or more different wireless carriers and identify corresponding UEs and RF signal repeater devices that correspond to the different wireless carriers. Also, the BMA may employ one or more RF signal repeater devices to identify “white zones” where no wireless communication is unavailable for UEs to communicate with wireless base stations by routes provided by the RF signal repeater devices over a wireless network.

Also, in one or more embodiments, the BMA may be provided as a locally hosted application, a cloud application, or a hybrid cloud application in communication with an EMS for one or more wireless networks.

Illustrated Operating Environment

FIG. 1A illustrates one embodiment of a holographic metasurface antenna (HMA) which takes the form of a surface scattering antenna 100 that includes multiple scattering elements 102 a, 102 b that are distributed along a wave-propagating structure 104 or other arrangement through which a reference wave 105 can be delivered to the scattering elements. The wave propagating structure 104 may be, for example, a microstrip, a coplanar waveguide, a parallel plate waveguide, a dielectric rod or slab, a closed or tubular waveguide, a substrate-integrated waveguide, or any other structure capable of supporting the propagation of a reference wave 105 along or within the structure. A reference wave 105 is input to the wave-propagating structure 104. The scattering elements 102 a, 102 b may include scattering elements that are embedded within, positioned on a surface of, or positioned within an evanescent proximity of, the wave-propagation structure 104. Examples of such scattering elements include, but are not limited to, those disclosed in U.S. Pat. Nos. 9,385,435; 9,450,310; 9,711,852; 9,806,414; 9,806,415; 9,806,416; and 9,812,779 and U.S. Patent Applications Publication Nos. 2017/0127295; 2017/0155193; and 2017/0187123, all of which are incorporated herein by reference in their entirety. Also, any other suitable types or arrangement of scattering elements can be used.

The surface scattering antenna may also include at least one feed connector 106 that is configured to couple the wave-propagation structure 104 to a feed structure 108 which is coupled to a reference wave source (not shown). The feed structure 108 may be a transmission line, a waveguide, or any other structure capable of providing an electromagnetic signal that may be launched, via the feed connector 106, into the wave-propagating structure 104. The feed connector 106 may be, for example, a coaxial-to-microstrip connector (e.g. an SMA-to-PCB adapter), a coaxial-to-waveguide connector, a mode-matched transition section, etc.

The scattering elements 102 a, 102 b are adjustable scattering elements having electromagnetic properties that are adjustable in response to one or more external inputs. Adjustable scattering elements can include elements that are adjustable in response to voltage inputs (e.g. bias voltages for active elements (such as varactors, transistors, diodes) or for elements that incorporate tunable dielectric materials (such as ferroelectrics or liquid crystals)), current inputs (e.g. direct injection of charge carriers into active elements), optical inputs (e.g. illumination of a photoactive material), field inputs (e.g. magnetic fields for elements that include nonlinear magnetic materials), mechanical inputs (e.g. MEMS, actuators, hydraulics), or the like. In the schematic example of FIG. 1A, scattering elements that have been adjusted to a first state having first electromagnetic properties are depicted as the first elements 102 a, while scattering elements that have been adjusted to a second state having second electromagnetic properties are depicted as the second elements 102 b. The depiction of scattering elements having first and second states corresponding to first and second electromagnetic properties is not intended to be limiting: embodiments may provide scattering elements that are discretely adjustable to select from a discrete plurality of states corresponding to a discrete plurality of different electromagnetic properties, or continuously adjustable to select from a continuum of states corresponding to a continuum of different electromagnetic properties.

In the example of FIG. 1A, the scattering elements 102 a, 102 b have first and second couplings to the reference wave 105 that are functions of the first and second electromagnetic properties, respectively. For example, the first and second couplings may be first and second polarizabilities of the scattering elements at the frequency or frequency band of the reference wave. On account of the first and second couplings, the first and second scattering elements 102 a, 102 b are responsive to the reference wave 105 to produce a plurality of scattered electromagnetic waves having amplitudes that are functions of (e.g., are proportional to) the respective first and second couplings. A superposition of the scattered electromagnetic waves comprises an electromagnetic wave that is depicted, in this example, as an object wave 110 that radiates from the surface scattering antenna 100.

FIG. 1A illustrates a one-dimensional array of scattering elements 102 a, 102 b. It will be understood that two- or three-dimensional arrays can also be used. In addition, these arrays can have different shapes. Moreover, the array illustrated in FIG. 1A is a regular array of scattering elements 102 a, 102 b with equidistant spacing between adjacent scattering elements, but it will be understood that other arrays may be irregular or may have different or variable spacing between adjacent scattering elements. Also, Application Specific Integrated Circuit (ASIC) 109 is employed to control the operation of the row of scattering elements 102 a and 102 b. Further, controller 110 may be employed to control the operation of one or more ASICs that control one or more rows in the array.

The array of scattering elements 102 a, 102 b can be used to produce a far-field beam pattern that at least approximates a desired beam pattern by applying a modulation pattern 107 (e.g., a hologram function, H) to the scattering elements receiving the reference wave (ψ_(ref)) 105 from a reference wave source, as illustrated in FIG. 1B. Although the modulation pattern or hologram function 107 in FIG. 1B is illustrated as sinusoidal, it will be recognized non-sinusoidal functions (including non-repeating or irregular functions) may also be used. FIG. 1C illustrates one example of a modulation pattern and FIG. 1D illustrates one example of a beam generated using that modulation pattern.

In at least some embodiments, a computing system can calculate, select (for example, from a look-up table or database of modulation patterns) or otherwise determine the modulation pattern to apply to the scattering elements 102 a, 102 b receiving the RF energy that will result in an approximation of desired beam pattern. In at least some embodiments, a field description of a desired far-field beam pattern is provided and, using a transfer function of free space or any other suitable function, an object wave (ψ_(obj)) 110 at an antenna's aperture plane can be determined that results in the desired far-field beam pattern being radiated. The modulation function (e.g., hologram function) can be determined which will scatter the reference wave 105 into the object wave 110. The modulation function (e.g., hologram function) is applied to scattering elements 102 a, 102 b, which are excited by the reference wave 105, to form an approximation of an object wave 110 which in turn radiates from the aperture plane to at least approximately produce the desired far-field beam pattern.

In at least some embodiments, the hologram function H (i.e., the modulation function) is equal the complex conjugate of the reference wave and the object wave, i.e., ψ_(ref)*ψ_(obj). In at least some embodiments, the surface scattering antenna may be adjusted to provide, for example, a selected beam direction (e.g. beam steering), a selected beam width or shape (e.g. a fan or pencil beam having a broad or narrow beam width), a selected arrangement of nulls (e.g. null steering), a selected arrangement of multiple beams, a selected polarization state (e.g. linear, circular, or elliptical polarization), a selected overall phase, or any combination thereof. Alternatively, or additionally, embodiments of the surface scattering antenna may be adjusted to provide a selected near field radiation profile, e.g. to provide near-field focusing or near-field nulls.

The surface scattering antenna can be considered a holographic beamformer which, at least in some embodiments, is dynamically adjustable to produce a far-field radiation pattern or beam. In some embodiments, the surface scattering antenna includes a substantially one-dimensional wave-propagating structure 104 having a substantially one-dimensional arrangement of scattering elements. In other embodiments, the surface scattering antenna includes a substantially two-dimensional wave-propagating structure 104 having a substantially two-dimensional arrangement of scattering elements. In at least some embodiments, the array of scattering elements 102 a, 102 b can be used to generate a narrow, directional far-field beam pattern, as illustrated, for example, in FIG. 1C. It will be understood that beams with other shapes can also be generated using the array of scattering elements 102 a, 102 b.

In at least some of the embodiments, the narrow far-field beam pattern can be generated using a holographic metasurface antenna (HMA) and may have a width that is 5 to 20 degrees in extent. The width of the beam pattern can be determined as the broadest extent of the beam or can be defined at a particular region of the beam, such as the width at 3 dB attenuation. Any other suitable method or definition for determining width can be used.

A wider beam pattern (also referred to as a “radiation pattern”) is desirable in a number of applications, but the achievable width may be limited by, or otherwise not available using, a single HMA. Multiple instances of HMAs can be positioned in an array of HMAs to produce a wider composite far-field beam pattern. It will be recognized, however, that the individual beam patterns from the individual HMAs will often interact and change the composite far-field beam pattern so that, at least in some instances, without employing the one or more embodiments of the invention, the simple combination of the outputs of multiple instances of HMAs produces a composite far-field beam pattern that does not achieve the desired or intended configuration.

FIG. 1E illustrates an arrangement of HMAs 120 a, 120 b, 120 c that produce beams 122 a, 122 b, 122 c where the middle beam 122 b is substantially different in size and shape from the other two beams 122 a, 122 c. FIG. 1F illustrates, in a top view, yet another arrangement of HMAs 120 a, 120 b, 120 c, 120 d which form a two-dimensional array.

Also, one or more particular shapes of beam patterns, such as wide beam patterns, narrow beam patterns or composite beam patterns, may be desirable in a number of applications at different times for different conditions, but may not be practical or even available using a single HMA. In one or more embodiments, multiple instances of HMAs may be positioned in an array to produce a wide variety of composite, near-field, and/or far-field beam patterns without significant cancellation or signal loss. Since the object waves of multiple instances of HMAs may interfere with each other, adjustment to their object waves may be desirable to generate a beam pattern “closer” to the desired shape of a particular beam pattern. Any suitable methodology or metric can be used to determine the “closeness” of a beam pattern to a desired beam pattern including, but not limited to, an average deviation (or total deviation or sum of the magnitudes of deviation) over the entire beam pattern or a defined portion of the beam pattern from the desired beam pattern or the like.

In one of more embodiments, a physical arrangement of HMAs may be existing or can be constructed and coupled to a reference wave source. In one or more embodiments, a hologram function can be calculated, selected, or otherwise provided or determined for each of the HMAs. Each of the HMAs includes an array of dynamically adjustable scattering elements that have an adjustable electromagnetic response to a reference wave from the reference wave source. The hologram function for the HMA defines adjustments of the electromagnetic responses for the scattering elements of the HMA to produce an object wave that is emitted from the HMA in response to the reference wave. The object waves produced by the HMAs may be combined to produce a composite beam. Any suitable method or technique can be used to determine or provide any arrangement of HMAs to produce a composite beam, such as the exemplary composite beams illustrated in FIGS. 1E and 1F.

FIG. 2B illustrates an exemplary schematic overview 220 of RF signal repeater device 222, which is coupled to Angle of Arrival (AoA) antenna array component 224, one or more optional wireless base station omnidirectional/sector directional antenna components 226, one or more optional UE omnidirectional/sector directional antenna components 237, one or more beam antenna components 228 that may be used to communicate with one or more UEs, wireless base stations, or other RF signal repeater devices, and one or more optional radio frequency RF inputs (not shown) connected to one or more optional radio frequency (RF) downlink ports 230. In one or more embodiments, a physical connection between the one or more RF inputs and the one or more downlink RF ports 230 is provided by one of a coaxial fiber cable, a waveguide, or another conductive component that is arranged to communicate downlink RF signals between RF signal repeater device 222 and one or more wireless base stations.

In one or more embodiments, RF signal repeater device 222 may be arranged to operate as a donor unit device that relays RF signals with the beam antennas between one or more wireless base stations, or other RF signal repeaters that are arranged to operate as other donor unit devices or a service unit device. Additionally, the RF signal repeater device may be arranged to operate as a service unit device that communicates the RF signals to one or more UEs that are provided by one or more wireless base stations or other RF signal repeater devices that are arranged to operate donor unit devices.

RF signal repeater device 222 includes system controller 238 which manages the operation of several components, including AoA detector component 232, downlink protocol decoder component 234, antenna controller 236, and optional orientation detector component 239. AoA detector component 232 is coupled to AoA array antennas component 224.

As shown, AoA detector component 232 is arranged to employ AoA antenna array 224 to determine an azimuth and an elevation that best fits uplink wireless RF signals communicated to a wireless base station by remotely located UEs. Also, AoA detector component 232 may use a schedule provided by downlink protocol decoder component 234 to sort, in time and frequency, digitized data corresponding to the wave forms of each of the received uplink wireless RF signals so that the data received from each UE can be processed independently and separately identify each UE that is communicating with the wireless base station at a scheduled time. AoA detector component 232 provides a table of identifiers for each UE along with their azimuths and elevations relative to AoA antenna array 234, which is associated with the schedule provided by the downlink protocol decoder component.

As shown, downlink protocol decoder component 234 employs downlink RF signals communicated by the wireless base station through one or more RF inputs that are connected to one or more wireless base station RF downlink ports 230 to determine the schedule employed by the wireless base station to communicate with a plurality of identified UEs. Downlink protocol decoder component 234 monitors the downlink RF signals for control information by decoding its corresponding one or more wireless communication protocols, which in some circumstances may include a 4G protocol such as Long Term Evolution (LTE).

Additionally, an exemplary decoding process employed by downlink protocol decoder component 234 for the LTE protocol includes at least in part as follows: (1) synching to the primary and secondary synchronization signals to determine a cellular ID and time for synching for each UE; (2) decode a Management Information Database (MIB) to determine the bandwidth of the wireless base station's communication with the UE; (3) extract Physical Control Format Indicator Channel (PCFICH) to determine control region numerology that is used in the Physical Downlink Control Channel (PDCCH); (4) blind decode each possible PDCCH to identify the scheduling information; and (5) employ the physical download shared channel (PDSCH) information to decode a system information block that is used to determine the uplink bandwidth. The result of the decoding process for the LTE protocol is determining a schedule that identifies a time and a frequency allocation for each UE for transmitting and receiving wireless RF signals with the wireless base station. In this way, downlink protocol decoder component 234 is able to provide the determined schedule to AoA detector component 232 and antenna controller component 236. Additionally, a similar decoding process, albeit different in some ways, may be employed to decode other wireless communication protocols, such as other 4G protocols and/or 5G protocols.

As shown, downlink protocol decoder component 234 employs an RF input (not shown) connected to wireless base station RF downlink port 230 to monitor downlink RF signals for control information broadcast by the wireless base station. In one or more embodiments, the control information is not encrypted or encoded. Further, in one or more embodiments, downlink protocol decoder component 234 does not decrypt or read user data communicated between the wireless base station and one or more UEs. Further, in one or more embodiments, a wireless service provider or carrier that controls the wireless base station may not know a location of each identified UE that is in communication with the wireless base station. Also, the control information may include a schedule for the wireless base station that allocates a time period when each identified UE is enabled for communication of wireless signals (uplink and downlink) with the wireless base station.

Furthermore, downlink protocol decoder component 234 may provide additional information regarding one or more of the identified UEs in communication with the wireless base station to the carrier which controls the wireless base station or another carrier for different purposes, including emergency services, security services, advertising or marketing. The provided information may include one or more of azimuth, elevation, carrier, or a determined location of one or more identified UEs, or a strength of wireless signals communicated between the UE and one or more beam antennas operated by antenna controller component 236.

In one or more embodiments, antenna controller component 236 generates a pointing schedule based on a combination of the allocation schedule provided by downlink protocol decoder component 234 and the table provided by AoA detector component 232. The pointing schedule includes the azimuth, elevation, and time schedule for transmitting and receiving wireless signals with each UE identified to be in communication with the wireless base station. In one or more embodiments, the pointing schedule may also include a strength of uplink wireless signals communicated by identified UEs, and one or more waveforms employed by a beam forming antenna to radiate a beam of wireless signals in the direction of each identified UE.

Also, in one or more embodiments, antenna controller component 236 may employ the one or more waveforms to configure the one or more beam forming antennas 228 to generate a beam of wireless downlink RF signals broadcast by the wireless base station at a scheduled time in the direction defined by the azimuth and elevation corresponding to each identified UE listed in the pointing schedule. Additionally, in one or more embodiments, antenna controller component 236 may provide a gain for the beam of wireless downlink RF signals radiated in the direction of an identified UE based on a strength of uplink wireless RF signals from identified UEs that are monitored by AoA detector component 232 with AoA antenna array 224.

Additionally, in one or more embodiments, the antenna controller component 236 may receive downlink wireless RF signals communicated by the wireless base station for each identified UE on the schedule with one or more of the optional omnidirectional/sector directional wireless base station antennas 226. In this way, RF signal repeater device 222 may employ wireless base station antennas 226 to receive the downlink RF signals wirelessly transmitted by one or more types of antennas (not shown) employed by the wireless base station (not shown). Further, the received downlink RF signals may be retransmitted as a beam waveform that is radiated in the direction of each identified UE at the corresponding time periods allocated in the pointing schedule. Also, the antenna controller 236 can receive downlink RF signals communicated in 5G or 4G protocols from the wireless base station, and then multiplex the retransmission of the received downlink RF signals to each identified UE. Additionally, in one or more embodiments, the one or more beam antenna 228 may include one or more a holographic beam forming (HBF) antenna, a parabolic antenna, a spherical antenna, a helical antenna, a yagi antenna, a horn antenna, a phased array antenna, or the like.

As shown, optional orientation detector component 239 may be employed to identify a physical position of the RF signal repeater device 222 generally, and more specifically the orientation and physical position of the one or more beam antennas 228. Although not shown, orientation detector component 239 may include one or more of an accelerometer, gyroscope, compass, altimeter, or a global positioning system (GPS) component.

Additionally, as shown, system controller component 238 is in communication with AoA detector component 232, downlink protocol decoder component 234, antenna controller component 236, and optional orientation detector component 239. System controller component 238 is employed to manage and coordinate the operation of the other components. Also, in one or more embodiments, system controller component 238 is employed to communicate with one or more client computers (not shown) that are employed to remotely manage the operation of RF signal repeater device 222.

Also, the system controller component 238 may provide information regarding one or more of the identified UEs or non-identified UEs to one or more of carriers, organizations, or other entities, for different uses, e.g., emergency services, security services, advertising or marketing. The provided information may include one or more of azimuth, elevation, carrier associated with a UE, or strength of wireless RF signals communicated between the UE and the antenna controller component. Also, the provided information may include a determined location of a UE.

Additionally, in one or more embodiments (not shown in the figures), system controller component 238 may include one or more processor devices, or embedded logic hardware devices, such as, an Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), Programmable Array Logics (PALs), or the like, or combination thereof. The one or more processor devices or embedded logic hardware devices may directly execute one or more of embedded logic or logic stored in a memory to perform actions to manage the operation of other components. Also, in one or more embodiments (not shown in the figures), system controller component 238 may include one or more hardware microcontrollers instead of processor devices. In one or more embodiments, the one or more microcontrollers may directly execute their own embedded logic or logic stored in memory to perform actions and access their own internal memory and their own external Input and Output Interfaces (e.g., hardware pins and/or wireless transceivers) to perform actions, such as System On a Chip (SOC), or the like.

Additionally, in one or more embodiments, antenna controller component 236 may employ two or more waveforms to configure UE beam forming antenna component 228 to generate two or more separate beams at the scheduled time in different directions defined by two or more azimuth and elevation coordinate pairs that correspond to two or more identified UE listed in the pointing schedule and allocated a time period to communicate with the wireless base station.

Further, in one or more embodiments, antenna controller component 236 may employ two or more waveforms to configure two or more separate UE beam forming antennas 228 to generate two or more separate beams at the scheduled time in different directions defined by two or more azimuth and elevation coordinate pairs that correspond to two or more identified UE listed in the pointing schedule and allocated a time period to communicate with the wireless base station.

Moreover, in one or more embodiments, antenna controller component 236 may facilitate an arrangement of a two to one Multiple Inputs Multiple Outputs (MIMO) antenna by using both UE beam forming antenna 228 and optional UE omnidirectional/sector directional antenna 237 to provide communication with an identified UE during allocated time periods in the pointing schedule. In one or more embodiments, antenna controller component 236 may employ these two antennas to determine which antenna is able to provide the optimal, e.g., best bandwidth with the lowest latency to communicate downlink RF signals to an identified UE. Once the optimal determination is made for the identified UE, antenna controller component 236 may use the determined antenna for further communication of downlink RF signals with the UE.

Further, in one or more embodiments, antenna controller component 236 may employ both UE beam forming antenna 228 and optional omnidirectional/sector directional antenna 237 to simultaneously provide communication of wireless downlink RF signals to at least two different identified UEs that are simultaneously allocated time periods in the pointing schedule for communication with the wireless base station. Also, antenna controller component 236 may be arranged to employ one or more policies to determined which of these two antennas provides simultaneous communication with each of the at least two UEs. For example, a policy may prioritize communication by UE beam forming antenna 228 with a preselected UE, or the first UE to respond to wireless control signals, when simultaneous communication with two or more UEs occurs. Based on the policy, one UE may communicate via UE beam forming antenna 228 and the other UE would communicate via optional UE omnidirectional/sector directional antenna 237. Also, in one or more embodiments, antenna controller component 236 may provide one or more waveforms to the beam forming antenna to cause radiation of wireless downlink RF signals omnidirectionally instead of in a shaped beam for one or more identified UEs during an allocated time period on the pointing schedule.

Generalized Operations

FIG. 4A illustrates an embodiment of a logical flow diagram for an exemplary method 400 for registering a new RF signal repeater device in a wireless IoT network in accordance with key performance indicators for the network and user equipment. Moving from a start block, the process steps to block 402 wherein a newly commissioned RF signal repeater device is connected to an IoT wireless network. At block, 404, a cryptographic certificate for the new RF signal repeater device is provided to a separate Certificate Authority service for validation.

Next, at block 406, the beam management application employs validation of the certificate to register the new RF signal repeater device as an element of the wireless network. Stepping to block 408, the beam management application employs KPIs for the wireless network and the UEs to determine the arrangement of the RF repeater device as a service unit or donor unit in the wireless network.

At block 410, the beam management application updates wireless communication routing and KPIs for network and user equipment based on addition of newly registered RF signal repeater device on the wireless network. Further, the process moves to the return block and continues performing other actions.

FIG. 4B shows an embodiment of a logical flow diagram for an exemplary method 420 for detecting an anomaly or outage for a wireless IoT network and automatically remediating the anomaly or outage in accordance with key performance indicators for the network and user equipment. Moving from a start block to decision block 422, where the process continuously monitors as to whether an anomaly in the operation of an RF repeater device, an anomaly in a KPI, or an outage of one or more portions of a wireless network is occurring. Once the decision is affirmative, the process steps to block 424 where the process determines a recommendation for one or more remediation actions based at least in part on changes to KPIs for the wireless network and/or UEs.

At block 426, alerts are provided to users of the beam management application of detected anomalies/outages and recommendations for one or more remediation actions. Optionally, at block 428, the beam management application provides for automatic execution of the one or more recommended remediation actions. Also, users are alerted of the execution of the remediation and updates to the KPIs after the remediation actions were executed. Next, the process advances to the return block and continues performing other actions.

FIG. 4C illustrates an embodiment of a logical flow diagram for an exemplary method 430 for modeling operation of each RF signal repeater device and modeling the corresponding network to virtually determine effects on key performance indicators for the network and user equipment before changes are applied to the operation of the actual RF signal repeater device.

Moving from a start block, the process steps to block 432 where machine learning may be employed to automatically generate a model for each RF signal repeater that is registered in the network. Also, machine learning may be employed to automatically generate a network model that corresponds to the arrangement of the RF signal repeater device as one of a service unit or a donor unit and node relationships to other elements in the network that would be defined by a number of degrees of association. Next, the process flows to block 434 where a virtual digital twin of each RF signal repeater is generated based on the RF signal repeater model and network model corresponding to an actual RF signal repeater registered on the wireless network.

Stepping to block 436, prospective changes intended for actual RF signal repeater are applied to the digital twin to simulate and test effects of changes to KPIs for digital twin and network simulated with the corresponding network model. Further, at block 438, the simulated KPI effects are employed to iteratively update the RF signal repeater model and network model until negative KPI effects are removed in simulated testing of the prospective changes applied to the digital twin.

Further, at block 438, the updated RF signal repeater model and updated network model are employed to update the RF signal repeater and apply the originally prospective changes. Next, the process moves to the return block and continues performing other actions.
